You have two forces, 106.8 N and 50.8 N.
What is their resultant if the first acts upward and the second acts downward?
What is the direction of the resultant?
What is their resultant if they both act downward?
What is the direction of this resultant?
I will be happy to critique your thinking on this fundamental concept.
Cmon man
To find the resultant of two forces, you can use the concept of vector addition. The resultant is the sum of the two forces, taking into account their magnitude and direction.
1. When the first force of 106.8 N acts upward and the second force of 50.8 N acts downward, the resultant can be calculated by subtracting the magnitude of the second force from the magnitude of the first force:
Resultant = 106.8 N - 50.8 N = 56 N
To determine the direction of the resultant, we look at the vector directions of the forces. In this case, since the first force is upward and the second force is downward, the resultant will have a direction upward.
2. If both forces act downward, the resultant can be found by adding the magnitudes of the two forces:
Resultant = 106.8 N + 50.8 N = 157.6 N
Again, considering the directions of the forces, when both forces act downward, the resultant will also have a downward direction.
In summary:
1. Resultant when the first force acts upward and second force acts downward: 56 N, with an upward direction.
2. Resultant when both forces act downward: 157.6 N, with a downward direction.
